To all whom it mcy concern:

'Be' it known thatI, Houses A. Romsos, of Cleveland, in the county of Guyahoga, and State of Ohio, have invented a certain new and improved Weather- Strip; and Ida hereby declare thatt-he following is a.

. full, clear, and complete description of theesame, reference being had'to the'accompahying drawings making to me December 24, "1867.

By'snidimproven ent the stripimay be more easily adjusted to thedoor and sill, and the'lower section will more readily turn or vibrate upon the elastic hinge .in opening and closing the door; also, its general construction and arrangement is more durable, as herein after set forth, than thatdescribed in the aforesaid Letters Paten 7 4 To enable others to understand the construction and operation of my improved weather-strip, I willproceed to describe it with reference to the annexeddrawings. v

A, in figs. 1 and 3, is designed to represent the part of a door to which the weather-strip is attached, which n is composed of two sections, B B, and united by a continuous elastic s rin -hin e 0' ti s-2am 3. 7 7 t:

This hinge allows the section B adjust itself to the desired position, and extends the entire length of each section, as indicated by the dotted lines 0 c in grooves D D.

These grooves-are placed in an angular position in relation to the sections B B, as seen in fig. 3, in such way that-the ofiice of the hinge G will aid, in connection with the spring E, in moving out the section B from B" to B, when the dooris 0pen,and also to connectthe two sections together. i p The hinge (l of itself is not sui licient or durable enough to form a reliable hinge, hence the utility of the spring E. v l

V When the door isclosed,the section B'assnmes the position indicated at B", as there is a lug or stop attached to the door-casing against which the section B is brought in contact, and causes it to turn from B to B". in closing the door, so as to bring the rubber E in ,close contactwith the door-sill forthe purpose desired. There may be one, two, or more springs E connected with the weather-strip in accordance with the width of the door or length of said strip.

moving it out,so as to turn upon the hinge C, as seen I in fig. 3.

I The strip is fastened to the door by means of screws =G, figs. 1 and 3,-Wlli0ll passthrough oblong slots noted by dotted lines a in section B, fig. .1. By means of these slots the weather-strip may be readily adjustedto the door in the desired position, and secured-with the screws.

the purpose. v

It is found that the spring for moving out the section :B, when made of rubber, becomes iuoperativeby the stiffening of the rubber and by displacement and by the action of the weather. In summer, when is exposed places, the rubber becomes so softened as to become unserviceable, and when subject to the influence of cold it soon loses its elasticity by becoming so hard and rigid as to render the weather-strip inoperatire for the purpose desired. I

But by the use of the spring E these objections are avoided, anda durable and elastic movement to the section B is at all times insured.

From the lower part of section B is a lip, H, seen in .fig. 3, which extends down and up over the upper part of section B, to exclude dust, rain, 85c.
